Tips to safeguard websites

1. Keep minimum number of resources online.

2. do password protection of internally accessed resources.

3. Do regular website scanning. Acunetix is one good tool.

4. Engage security consultants to do security audits. www.securityescape.com  is one recommended by me.

5. Check folder permissions. use 755 as default permission. 

6. Be very extra careful with uploading files. 

7. Use WSO.php to understand damage possible if any file uploaded successfully.

8. Keep code and data separately. use php engine off on data folders.

Google play store formatting

• Single line breaks are ignored; double line breaks open a new paragraph.
• Single line breaks can be enforced by ending a line with two spaces (similar to Markdown).
• A limited set of HTML tags (optionally nested), specifically:
  • <b>…</b> for boldface,
  • <i>…</i> for italics,
  • <u>…</u> for underline,
  • <br /> to enforce a single line break,
  • I could not find any way to get strikethrough working (neither HTML or Markdown style).
• A fully-formatted URL such as http://google.com; this appears as a hyperlink.
  (Beware that trying to use an HTML <a> tag for a custom description does not work and breaks the formatting.)
• HTML character entities are supported, such as → (→), ™ (™) and ® (®); consult this W3 reference for the exhaustive list.
• UTF-8 encoded characters are supported, such as é, €, £, ‘, ’, ★ and ☆.
• Indentation isn't strictly possible, but using a bullet and em space character looks reasonable (•  yields "• ").
• Emoji are also supported (though on the website depends on the user's OS & browser).

Special notes concerning only Google Play app:

• Some HTML tags only work in the app:
  • <blockquote>…</blockquote> to indent a paragraph of text,
  • <small>…</small> for a slightly smaller text,
  • <sup>…</sup> and <sub>…</sub> for super- and subscripts.
  • <font color="#a32345">…</font> for setting font colors in HEX code.
• Some symbols do not appear correctly, such as ‣.
• All these notes also apply to the app's "What's New" section.

Special notes concerning only Google Play website:

• All HTML formatting appears as plain text appears in the website's "What's New" section (i.e. users will see the HTML source).
